Title: Game machine
Inventor: UGAWA SHOHACHI
IPC: A63F7/02
Filed: 2000-08-09
Abstract: PROBLEM TO BE SOLVED: To prevent controls from being disturbed even when an instantaneous interruption of a power source to be restored for a short time or the like occurs and to easily clear a preserved control state in a game machine constituted so as to preserve the control state at the time of an unpredicted power interruption or the like. SOLUTION: When the instantaneous interruption of the power source or the like occurs, the voltage level of VSL lowers for a short period and then is restored. When the voltage level of the VSL becomes a power interruption signal output level or lower, power interruption signals become a low level and a power supply stop time processing is started. Then, a CPU enters a loop state after the power supply stop time processing is ended. When a power supply voltage is restored, a counter counts up and recovery signals are generated. Since the recovery signals are inputted to the reset terminal of the CPU, the CPU can get out of a loop by system reset. Also, at the time of performing activation by the system reset, when a clear switch is on, a RAM clearing processing is performed.
